Powerstack: Meta and Entergy go for 7.2GW gas in Louisiana

Hi there,

Meta just announced it’s planning the largest purpose-built power system for a single corporate end-user in US history for its Louisiana data center. It’s a risky proposition -- we get into why below.

Plus, the NRC’s new rules, Mistral’s debt raise, and more below.

Meta tripled its Louisiana data center buildout to 7GW across 10 dedicated gas plants, 240 miles of new transmission, and 2.5GW of solar -- reportedly the largest purpose-built power system for a single corporate end-user in US history. Meta is paying and Entergy is building, all under automatic rate basing. Both say the expansion will save ratepayers $2.65bn, but consumer advocates say it transfers risk from a trillion-dollar tech company to Louisiana households. Meta has a 4-year lease exit window, which could be at odds with the 30-year lifetime of these assets.

Meta's Hyperion campus in Richland Parish started as a 2.3GW announcement in early 2024. Last week, Meta announced an expansion to ~7.5GW. Let’s break it down:

Local power company and partner Entergy will build, own, and operate everything. The plants enter the rate base automatically through Entergy's Formula Rate Plan -- no separate rate case for each unit, the cost of each installed unit just slides right in. Meta would fund at least 50% through a dedicated large-load tariff under the Lightning Amendment, a fast-track mechanism approved in 2025 that cuts regulatory review from two years to eight months and suspends competitive bidding. 

Meta's campus is held through Beignet Investors LLC, backed by a $27bn private credit facility from Blue Owl Capital with a 4-year lease and rolling extensions. And the expanded project is requesting Lightning Amendment fast-track review. The Lightning Amendment requires Meta to cover "at least half" of new power plants costs. But that's half the cost for half the depreciable life -- a 15-year contract on a 30-year plant. So, that could mean Meta might be on the hook for at minimum 25% of the total lifecycle cost, with ratepayers absorbing the other 75%. There is no requirement for Entergy shareholders to share the gap. Any cost overruns flow through the Formula Rate Plan automatically to Entergy Louisiana customers.

Over the past few years, gas plant costs have risen from ~$1,000/kW to $2,000-$2,500/kW or more (some estimates put it at $3,620/kW). Couple that with oversubscribed demand for gas turbines, and labor shortages, these prices could go higher still. With the Formula Rate Plan, this could spell real risk for Louisiana consumers. 

For Meta, Louisiana is the strategy.

I've been closely watching US power projects for decades, and Hyperion reads like a new chapter in the same old story. Regulated utilities propose huge-capex projects, commissions approve them under frameworks that spread the risk and cost across the ratepayer base, and hope and pray that things stick to time and budget. When they don't, residential customers absorb the cost. That’s particularly been true in the South.

My first thought when diving into this case was, let's see what happens at the PSC, as the expansion still needs to be approved, and there’s been a lot of public opposition lately – the public comments are sure to be scorching. But looking back at Louisiana PSC voting history – this thing is gonna go through. The LPSC voted 4-1 to approve the initial Richland Parish project, 4-1 to fast-track it, and 4-1 to not engage when the financing changed. This expansion is, therefore, as good as approved.

Other states are unlikely to see Hyperion as a shining star to follow (pun very much intended). Ohio's PUCO rejected Amazon and Google's attempt to overturn a protective large-load tariff. Virginia's SCC imposed 14-year commitments and 85% minimum demand payments on data centers. Pennsylvania's PUC split 3-2 on a model tariff. Minnesota passed a law requiring data centers to cover full cost of service with no stranded asset risk to ratepayers. Georgia and Indiana still vote like Louisiana, but in Georgia, they voted to freeze rates until 2028 while they figure all this out. The trend is moving toward ratepayer protection, not away from it. 

But when it comes to Hyperion, White House pledges alone aren't going to cut it.

Entergy gets a generational capex cycle -- 10 new gas plants, 240 miles of transmission, 2.5GW of solar procurement, and a nuclear development pipeline, all with a creditworthy anchor tenant. The deal locks in rate base growth for a decade-plus and positions Entergy as the template for regulated utility-hyperscaler partnerships. 

Gas turbine OEMs (GE Vernova, Siemens Energy, Mitsubishi) get another massive order signal into an already-stretched backlog. If they’re not at name-your-price yet, they’re getting close.

Solar developers in MISO South get a 2.5GW procurement signal in a region where utility-scale solar has lagged. 

Louisiana residential ratepayers are the ultimate backstop. The 4-year lease exit window vs. 30-year plant lifetime mismatch is real, the FRP means cost overruns flow through automatically, and the LPSC has shown no appetite to stress-test the departure scenario. Consumer advocates nationally worry this sets a precedent that fast-tracks hyperscaler generation using formula rate plans and lightning amendments to bypass deliberative rate case processes.

Louisiana industrial ratepayers -- the Exxons, Chevrons, and Shells operating refineries in Louisiana -- opposed even the original three-plant deal on grounds it would raise their costs. At triple the scale, the grid-wide cost allocation becomes a bigger fight.

A quick read on the numbers shaping the market, pulled from more than 10,000 signals filtered through the Sightline Climate platform every week. The capex, the contracts, the regs, all anchored in the so-what.

18 months // Expected time to approve new nuclear reactors under the US Nuclear Regulatory Commission’s new technology-inclusive licensing framework for advanced reactors, Part 53. It’s the first new set of reactor licensing regulations since 1989 and the most fundamental update since 1956. It removes the biggest regulatory bottleneck to deploying SMRs and other advanced reactors as hyperscalers bank on the tech to meet AI demand.

$830m // French AI startup Mistral’s debt raise, to buy Nvidia chips that will power a 44MW data center near Paris. It’s the French company's first debt, financed by a consortium of seven banks, and a real milestone for European AI sovereignty. However, it accidentally reveals that a record debt raise in Europe is a rounding error in the US hyperscaler capex cycle.

120GW // Planned European renewables at risk of being "stranded" due to grid bottlenecks, according to a new report. Europe's grid was built around centralized coal and gas plants, but renewables are in remote areas. While grid investment has risen ~50% to €70bn annually, congestion costs hit €9bn in 2024 and 72TWh of mostly renewable energy was curtailed. With the Iran war spiking oil and gas prices, grid constraints are threatening to strand the very projects meant to replace imported fossil fuels.

1.3GW // Michigan’s six latest approved BESS projects, including three between DTE Energy and Oracle. That’s 332MW dedicated to Oracle's data center, and Oracle contractually obligated to fund a total of 1.4MW over 15 years. BYOC coming to BESS -- not generation, just storage – could be a really fast and cheap way to interconnect data centers in areas with sufficient generation but insufficient peak capacity.

The policies, rulings, and company moves worth watching.

DOE's $1.9bn SPARK grid modernization opportunity. The DOE posted one of its biggest funding opportunities yet for grid projects, with a focus on reconductoring, advanced transmission, and cross-regional upgrades and coordinated planning.

PJM's co-location proposal drawing heavy fire. Vistra, the Data Center Coalition, and others are pushing back on PJM's plan to let data centers co-locate generation behind the meter. "Even a customer that brings sufficient co-located generation to meet its load cannot avoid curtailment risk," the Data Center Coalition told FERC. Meanwhile, PJM's new Connect-and-Manage Task Force launched March 31 to explore letting data centers interconnect faster in exchange for accepting curtailment risk. Two threads pulling in different directions — watch how FERC balances reliability concerns against the pressure to get load connected faster.

Constellation looking for a workaround on the Three Mile Island restart timeline. After PJM flagged that transmission upgrades for the Crane Clean Energy Center (the rebranded TMI) might not be ready in time, potentially pushing the commercial operation date to 2031, Constellation has asked whether it can transfer interconnection rights from an existing gas plant to Crane. A creative move among standard long nuclear restart timelines.

Colorado suing DOE over the Craig 1 coal unit extension. DOE issued an emergency order keeping the plant open past its planned closure, citing grid reliability and AI data centers and manufacturing demand. But the plant's co-owners and the state say they've already replaced the unit's energy capacity. This is a test case for how far DOE's emergency authority stretches.
